Apple, Go Get Ron Johnson Back. Now.

Way back in June 2011 when Apple lost retail chief Ron Johnson to J.C. Penney , it was seen as a huge loss for Apple and a big win for J.C. Penney. Johnson accepted the promotion, becoming CEO of the struggling department store chain. Nearly two years later, it would seem that Johnson wasn't such a victory for J.C. Penney after all.

Shares lost 55% of their value under his tenure (not including the 12% drop the following day after Johnson's predecessor, Mike Ullman, was rehired). J.C. Penney is an entirely different breed of retailer compared to the Mac maker. Johnson's strategy of removing discounts, coupons, and sales in favor of more transparent pricing didn't resonate with consumers, and J.C. Penney's sales suffered for it.

Well, as luck would have it, Johnson's former position at Apple is still up for grabs, following John Browett's departure in October. Since then, Apple has been searching for a new retail chief, with retail operations falling under CEO Tim Cook's jurisdiction in the interim. Browett came from the U.K.'s Dixons chain, and the British exec later said that he simply "just didn't fit" at Apple, maintaining that he wasn't rejected for a lack of competency. Browett failed to see the big picture, trying to save costs without realizing that cost cutting is the last thing that Apple should do, especially if the customer experience is the thing getting shortchanged.

Apple Retail has been doing just fineSince Johnson's departure, it's not as if Apple's retail operations have struggled. Far from it -- Apple retail has grown and has now generated $19.2 billion in trailing-12-month sales.

The company has also expanded its total store count by 74 stores to 401, up from 327 when he left. Most of this expansion has been internationally, as Apple's domestic retail footprint is rather mature and the company is rightly focusing abroad.

Foot traffic is also up, with record 120 million visitors last quarter. Average quarterly revenue per store is also flirting with all-time highs at $16.3 million in the fourth quarter.

Clearly, Apple isn't in dire need of Johnson to return. But at the same time, Apple Retail lacks dedicated leadership right now, and Johnson gets Apple. This is the guy that launched Apple Retail in the first place, promptly silencing critics that initially derided the move as misguided and doomed to fail. The Genius Bar is now the paragon of modern customer tech support, the type of notion that's mostly lost in a department store environment.

Other tech giants have since tried to emulate Apple's retail strategy, most notably Microsoft and Samsung. Microsoft Retail stores bear more than a passing resemblance to Apple's. The software giant's retail footprint remains young, but it continues to broaden its horizons. Microsoft still doesn't report retail revenue, but did cite the growing network as a contributing factor to its 41% jump in corporate-level expenses last quarter.

Just because Apple should doesn't mean Apple willApple should grab Johnson back now. Unfortunately, that may not be likely. It would be uncharacteristic of Apple to ask for someone (other than Steve Jobs) to return to the company, and the whole reason that Johnson left in the first place was to pursue a challenge. Apple Retail is already a proven success, and would hardly represent a challenge for him.

Just because Apple should offer Johnson his old job back doesn't mean it will, or that he'd even accept it.

Speaking of Apple Retail, the company still has a long ways to go in expanding its store footprint in China. The Middle Kingdom is currently Apple's second-largest market, and Tim Cook firmly believes it will become the largest.
